Estimering av GPS pålitlighet och GPS/INS fusion
The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.
Framtagning av analysmetodik för uppslutning av kemiska produkter
The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise and repeatable method that would be able to be applied to the process of qualification and technical marking of chemical products at the company, OKG AB in Oskarshamn. A complete instruction for the decomposition equipment and the method of analysis was written. A number of parameters were chosen from the general method of the combustion equipment, which then was tested parallel with a simultaneous development of an appropriate ion chromatographic method.
Fackförening i internationalisering. En studie av sex fackklubbars gränsöverskridande.
This rapport examines six Swedish workplace unions, in manufacturing internationalised companies, degree of internationalised trade union work. The report is based on interviews with local shop stewards. All local workplace unions were in some form internationalised. They were placed in three different groups of strategies: Passive, Tactical and Strategic. The Passive union only tried to get information; the Tactical unions were reactive against initiative from company management and used the channels provided of Industrial Relation laws.
Stopptids- och avvikelseuppfo?ljning vid la?nga takttider : Fra?n avvikelse till info?rd fo?rba?ttring
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.
Hållning av unga svenska islandshästar och dess påverkan på beteende hos tvååringar :
Icelandic horses are becomming increasingly common in Sweden. The owners of
Icelandic horses in Sweden usually believe their horses to be different from other
breeds. Icelandic horses are predominantly considered to be less reactive, less
neophobic and easier to handle than other breeds. Swedish owners of Icelandic
horses also usually try to house and handle their horses in a way similar to the
traditional extensive Icelandic way. There are no scientific studies of breed
differences between Icelandic horses and other breeds, or of the housing of
Swedish Icelandic horses.

Användarvänlighet i blötutfodring : enkätstudie för smågrisproducenter
It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.
Hållbar växtnäringshantering i Stockholms län : En aktörsanalys
Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.
OLED : Evaluation and clarification of the new Organic Light Emitting Display technology
Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.
Närsalter och bottenlevande organismer i Mönsteråsviken
The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.
Mineral composition of New Zealand monofloral honeys
The objective of this study was to determine the mineral content in ten New Zealand monofloral honeys, in order to distinguish whether New Zealand monofloral honeys are a good source of minerals compared to honeys from other parts of the world. The ten monofloral honeys were collected from a local honey factory (Airborne Honey Ltd, Leeston), Clover, Honeydew, Kamahi, Manuka, Nodding Thistle, Rata, Rewarewa, Tawari, Thyme and Vipers Bugloss honeys were been investigated. The water content, water activity, pH, conductivity, colour and mineral content were evaluated. The water activity was averaged for all the ten New Zealand monofloral honeys and set to 0.59 aw, which indicates a high stability and long shelf life as a food stuff. A strong correlation between total mineral content, pH, conductivity and colour was obtained.

Konstruktion av datainsamlingskort för mätsystemet COMET
During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.
Personlighetstyper och stressrespons hos djur ? med fokus på hund och häst
Animals living in captivity are often subjected to various kinds of stress. Individuals within species can respond differently to the same stressor depending on differences in coping style and physiology. Active and passive coping is a common way to describe different coping styles in animals and it is likely that these strategies have a high heritability. Individuals with an active coping style are characterized by an urge of control and a higher level of aggression than individuals with passive coping style, who in general are more flexible and respond to stress by immobilisation to a greater extent. The aim of this bachelor?s thesis is to investigate the presence of different coping styles and personality types in dogs (Canis lupus familiaris) and horses (Equus ferus caballus) and to find fields of application for this information.
Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder
It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.
